范文

The picture provided shows a man and his son out for a walk in what was once probably a beautiful landscape. The scene features wide open spaces, mountains, and a river. Behind the vast hills is a city. Unfortunately, the city has poisoned the surrounding environment. The hills are black and bare, the plains are home to no plants or animals, and the river is black and obviously polluted, as there are dead fish lining its banks.

This sad picture is meant to show us the error in our ways. In an ongoing quest to become more advanced and prosperous, we have failed to keep our home in a livable condition. We can no longer swim in the rivers that our fathers did, nor can we enjoy the peaceful serenity of nature. There is nothing left to take pleasure in.

I believe that we have a debt to future generations to clean up the mess we have made in the last one hundred years. We should enact laws that reward corporations that clean up their messes and punish those who continue to pollute. If the human race is going to continue to evolve and prosper, we must clean up our world.
